【摘要】：运用元件多状态可靠性理论建模可以克服传统二元模型进行可靠性评估造成信息遗失的缺点,提高评估结果的准确性。针对现有模型主要集中于元件渐变失效研究的现状,引入Markov过程后,阐述了元件多状态的定义,在元件多状态连续时间Markov过程推导的基础上,分别提出了元件发生渐变失效和突变失效的状态转移可靠性模型。并以某导弹延迟活门为例,建立同时发生渐变失效和突变失效的状态转移微分方程,确定了元件在指定水平下的可靠度函数,通过仿真获得了元件在确定时刻的可靠度,为基层级维修单位制定保障决策提供依据。
[Abstract]:The use of multi state reliability modeling element theory can overcome the traditional two element model to evaluate the reliability of information loss caused by faults, improve the accuracy of evaluation results. In view of the present situation of the existing model mainly focuses on the elements of gradual failure research, the introduction of Markov process, expounds the definition of multi state components, based on multi element state continuous time derivation of Markov on the gradual change of element are put forward the reliability model of failure and failure of the mutation state transfer. Taking a delay valve missile as an example, the establishment and gradual change of failure and failure of the mutation state transfer differential equation, determine the reliability function at the specified level of components were obtained through simulation in reliability to determine the time element and to provide the basis for maintenance units to make security decisions.
